Shielding is material which protects an area from electric or magnetic fields.
Some people shield spaces to prevent advanced hacking. Others feel weapons or surveillance systems are targeting them. Others feel something is communicating with their body or brain.
Please share your shielding projects. It can inspire others and help us collaborate.
There are three primary ways in which things can reach or affect your safe space. One or all of these may be affecting you:
* Electric fields and high-frequency electromagnetic radiation
Common forms include light and microwaves. Most information, nowadays, is sent via high-frequency electromagnetic radiation. They are blocked by covering an area in continuous conductive material, with no holes or gaps of any sort, not even seams. Spaces shielded in this way are used industrially to protect sensitive equipment.
* Magnetic fields and low-frequency electromagnetic radiation
A common form is AC power. Shielding from these signals is more difficulty and may involve a magnetic metal such as iron or steel. Researchers use strong magnetically shielded rooms to study the magnetic fields produced by the human brain.
* Physical vibrations
Common forms are sound, ultrasound, projectiles, earthquakes. These are blocked as sound would be.
All of these mediums share the attribute that high frequencies can store a lot of data and be directed very precisely, but cannot penetrate through a lot of material, whereas low frequencies cannot hold a lot of data, cannot be pointed or directed very well at all, but also will travel through most things.
To learn more, pursue classes in physics, electronics engineering, and electromagnetic compatibility. Classes, both free and paid, may be found around in the internet (links?). Please do study these things, get involved for the long haul, and share your work and education. Otherwise how will we move forward?
Although gasses, particle radiation, and nanomachines could also enter a secure space, these are not the problems to begin looking for. First secure against things which are reasonable threats. Then worry about obscure things, which are much, much harder to make use of.
